Dual exhaust ???

So i havre a 5.3 v8 gmc sierra 1500 with a k&n airintake. I currently have n xlerator dual exhaust system that is falling apart on me. So now i am looking for a new exhaust. most likely a different brand. I hear alot of positive feed back about cherry bomb exhaust and magna flow. Im looking to connect the new exhust from the stock y-pipe. I am also looking for an exhaust that angles at the ends so its pointing out on each corner of the rear end. I am also looking for a exhaust thats got a deepy sound to it, and not a high sounding one, more like a deep throaty sound.

its a 2002.. and will the magnaflow always have the deep rumble wheather its at idle or at cruising speed? heres a youtube video of what my current exhaust sounds like (its being seafoamed..) SeaFoam on a 02 sierra - YouTube
